Amid serious sexual assault allegations, Bill Cosby and his wife Camille Cosby may be headed for divorce as the victims' list of the stand up comedian keeps growing.

Ever since Hannibal Buress inadvertently accused his colleague of being a rapist, at least 18 women have come forward and revealed that Cosby has sexually abused them.

"He gets on TV, 'Pull your pants up, black people. I was on TV in the '80s. I can talk down to you because I had a successful sitcom.' Yeah, but you raped women, Bill Cosby, so turn the crazy down a couple notches," Buress said during his show in Philadelphia in mid-October, E Online reported.

The growing numbers of sex offences have reportedly humiliated his wife Camille, who is now considering officially splitting from her husband of 50 years, the National Enquirer reported.

A source told the tabloid that the couple has already survived many storms including "the tragic murder of their beloved son, and she bravely stood by Bill during the disclosure of an extramarital affair and a 'love child.'"

However, the comedian's wife has had enough when more victims came up to speak about the sexual assaults they suffered at the hands of Cosby and "there's only so much more she can take," the source added.

The serious accusations have also tarnished the family's image built by years of hard work.

"With one woman after another now coming forward, Bill's image is being destroyed, and all their years of hard work for charity and philanthropy are being tarnished," another source told National Enquirer.

"I know Camille is feeling humiliated by all this – and, even worse, she's come under personal attack."

The tabloid report claims that the sexual scandals could cost Bill a whopping $350 million if his wife seeks divorce.

However, Bill's nephew Braxton Cosby has dismissed the allegations against the 77-year-old comedian and said that his uncle is 'innocent'.

"I would be more inclined to compare it to the passage in the Bible where the people of the village were about to stone the woman caught in adultery and Jesus challenged them by saying that the person who is without sin should cast the first stone," Braxton told the People Magazine.

"The one difference in this case being that the woman was caught in the act and her accusers brought her forward. I want to remind everyone that we live in the greatest country in the entire world, one that prides itself on the moral law that everyone is innocent until proven guilty. That's where we stand at this time with the allegations brought against my uncle," he added.
